Update – 8 November 2026. EuroCTP switched on the EU consolidated tape for shares and ETFs on 14 September 2026, and its transition period ended on 30 September; the five-year operating term runs from the start of operations. The bond tape (fairCT) is still in ESMA’s authorisation process and will go live once it is connected to at least 80% of trading venues and APAs, representing at least 80% of traded volume. On OTC derivatives, ESMA updated its transparency manual on 15 October 2026 with draft guidance identifying in-scope OTC derivatives by UPI rather than ISIN; the derivatives changes are still expected to apply from 1 March 2027.

On 27 July 2026, ESMA authorised EuroCTP B.V. as the consolidated tape provider (CTP) for shares and ETFs, with a transition period running until 30 September 2026. For trading venues and APAs, the obligation to send data to the CTP applies from the day the service starts. For banks and investment firms, this is the EU’s first regulated, consolidated market data feed, and they need to decide now what role it will play in their systems.

What ESMA decided, and when

The MiFIR review (Regulation (EU) 2024/791) provides for one CTP per asset class. ESMA selects each provider through a tender for a five-year term, then authorises and directly supervises it. The technical standards on CTPs were published in the Official Journal of the EU on 3 November 2025.

For shares and ETFs, ESMA selected EuroCTP on 19 December 2025 and authorised it on 27 July 2026. The press release makes three points:

  • the transition period runs until 30 September 2026, to finalise the technical and operational set-up;
  • the five-year operating term starts on the date the service actually goes live, not on the authorisation date;
  • retail investors, academics, civil society organisations and regulators get the data free of charge. Other users pay a “reasonable” fee and may use the data internally and with clients.

On 1 April 2026, ESMA had already published Q&As on data contributor onboarding and on CTP operating rules. It reminded venues and APAs that they must contribute from go-live, and expected them to complete connectivity and end-to-end testing with the selected CTPs even before formal authorisation.

Three tapes, three timelines

The equity tape is only the first milestone. The other two asset classes are moving at different speeds.

Asset class Provider Selected Authorised Next known milestone
Shares and ETFs EuroCTP B.V. 19 December 2025 27 July 2026 End of transition period, 30 September 2026
Bonds Ediphy (fairCT) 3 July 2025 Ongoing, per ESMA’s CTP page No published go-live date
OTC derivatives Etrading Software (Netherlands) B.V. 6 July 2026 Invited to apply Derivatives RTS and CTP input/output data expected to apply from 1 March 2027

For derivatives, ESMA sent the Commission its final report on derivatives transparency, package orders and OTC derivatives CTP input and output data on 15 December 2025. It proposes a single application date of 1 March 2027, so that the new deferral regime is in place before that tape goes live.

The oddity is plain: the bond tape was tendered first, yet it has no public go-live date as the equity tape comes into service.

Why this is a compliance topic, not just a market data one

For a corporate and investment bank or an investment firm, the consolidated tape touches three functions at once.

Group venues and APAs. If your firm operates an MTF, an OTF, a systematic internaliser reporting through an APA, or the APA itself, contributing to the CTP is a legal obligation. The format relies on new ISO 20022 messages approved by the Registration Management Group. A transmission or data quality failure becomes a supervisory matter.

Best execution. Until now, each firm rebuilt its view of the European market from proprietary feeds. A consolidated, time-stamped feed that everyone can access changes the benchmark. Supervisors and clients will have a common reference in their reviews, and gaps between your execution reports and the tape will be easier to spot.

Market data costs. ESMA frames the CTP fee under a “reasonable” price principle. For procurement and data teams, the question is which proprietary feeds the tape replaces, which it complements, and when. That question calls for an inventory of use cases, not a decision from the top.

Regulatory watch

  • 23 September 2026, ESAs. In their Autumn 2026 risk update, the EBA, EIOPA and ESMA flag external dependencies (non-EEA ICT providers and infrastructure), cyber risks linked to advanced AI models and private credit as key vulnerabilities for the EU financial system. EBA press release
  • 25 September 2026, IASB. Its investor survey, launched on 4 September, on how financial institutions’ cash flow statements are used (IAS 7 project) closes today. It feeds the IASB’s work on a possible exemption for banks and insurers; results are due for discussion at a Q4 2026 meeting. IFRS Foundation

What this means for you

  1. Confirm your contributor status. List the venues, systematic internalisers and APAs in your group that fall in scope, and get evidence that end-to-end testing with EuroCTP has passed. Start the same work with fairCT for bonds now.
  2. Build the tape into your best execution framework. Document how the consolidated feed will, or will not, be used in execution quality controls and in the policy you present to clients. A written position beats a gap found during an inspection.
  3. Prepare the 2027 derivatives workstream. The new derivatives transparency and deferral regime is expected from 1 March 2027. Put post-trade publication configuration and testing with Etrading Software into the 2027 budget now.
